I'm trying to make a dvd from mpeg2 files. First of all i'm on windows 7. I'm using the following binaries: jpeg2yuv mpeg2enc mplex spumux dvdauthor Now everything is fine till this point absolutely no errors, but then i'm using mkisofs to make the iso file also no errors or warnings. It creates the iso file but i cannot burn it to dvd it said: The selected disk image file isn't valid. I tried it on a Mac osx as well and there the iso is worked fine. It is an NTSC iso. I'm totaly stuck with this problem any help is really appreciated.
